Access control policy is typically defined in terms of attributes, but in many applications it is more natural to define permissions in terms of relationships that resources, systems, and contexts
This paper shows that residence telephone calling rates (local calls per day) are related to household characteristics (e.g., number of members, age of the head).
In order to clarify which of two principle postulated sources of Pc 3 magnetic pulsations, i.e., upstream waves in the earth's foreshock and surface waves on the dayside magnetospheric boundary, do
In this paper we compute the relative class number of all imaginary Abelian fields of prime conductor below 10000.
An environmental stress testing (EST) program is being conducted at AT&T on various types of communications equipment.
Creep corrosion on printed circuit boards (PCBs) is the corrosion of copper metallization and the spreading of the copper corrosion products across the PCB surfaces to the extent that they may merg
A numerical method is proposed to accurately discriminate the influence of each intrachannel nonlinear effect.
Using X-ray diffraction techniques, one is able to routinely measure lattice parameters to several parts in 10(4) for microscopic specimens.
Czochralski and Bridgman methods for producing bulk single crystals of semiconductor materials are described. The relative merits of the various approaches are highlighted.
This paper will address the strengths and weaknesses of various methods for producing bulk single crystals of compound semiconductor materials.
